Power logic
The power related control logic is located in the power board.
Power ON/STBY control includes logic to switch the power supply on or off by turning the
ON/STBY switch. The ON/STBY line is fed by +7V (max. current 70mA). When this line is
grounded (for example by the ON/STBY switch), the DC Power supply switches on.
RESET_CPU signal is transmitted to the CPU interface in case the mains voltage fails or the
power is cut off. RESET signal is also generated for other digital boards.
Audio amplifier
Audio signal from the CPU is amplified and filtered for the loudspeaker. Amplification gain is
about 5 dB.
Protections
The following protections generate an automatic power off situation without any message in
advance.
1.
High voltage protection (+32 V, +15 V, +5 V, +5 Vcpu). Requires manual start-up. Power
cord must be disconnected shortly prior to the start-up.
2.
Low voltage protection (+32 V). Automatic power off when U < +25 V. Automatic start-up
after voltage is back to normal.
3.
High current protection (all secondary outputs). Output restrained until cause is
eliminated.
4.
High temperature protection. Automatic power off at +58 °C (approx.) and automatic
start-up at +48 °C (approx.).
